Answer:
G - 21%
T - 29%
A - 29%
Explanation:
Nucleotide bases in DNA are complementary. Adenosine (A) binds to Thymine (T) while Cytosine (C) binds to Guanine (G). Hence the composition of A in DNA is the same as that of T; and that of C is the same as that of G.
From the information given, C is 21%
Therefore G is also 21% of the genome as C is bound to G, the therefore are the same proportion.
C and G make up 42% of the genome (that 21% + 21%).
The remaining 58% (100%-42%) is made up of A + T
Similarly the proportion of A is equal to that of T,
Hence A is 29% (half of 58%) and T is 29%.
I think the answers are A, B, and C.
Answer:
<u>Part A</u> : 70 secondary oocytes will be formed.
<u>Part B</u> : 70 first polar bodies will be formed.
<u>Part C</u> : 70 ootids will be formed.
Explanation:
During oogenesis growth maturation of a single oogonium produces one primary oogonium.
the primary oogonium then undergoes meiosis -1 and produces one secondary oocyte and first polar body.
The secondary oocyte then undergoes meiosis - 2 and forms an ootid and second polar body.
The ootid then differentiates into the ovum.
As in the above scenario , 70 primary oocytes are present , they undergo meiosis-1 and produces 70 secondary oocytes and 70 first polar bodies. Hence answers of part A and B is 70.
As 70 secondary oocytes are formed , they undergo meiosis -2 and forms 70 ootids which then differentiate in 70 ovums.
A spider plant sends out runners that have buds. When planted, the bud grows into a mature plant. The resulting plant has one parent and is <u>genetically identical</u> to the parent.
Answer: Option C
<u>Explanation:</u>
Reproduction is of two types one is sexual reproduction and asexual reproduction. The asexual reproduction mostly involves only one parent and therefore the off spring that is born is genetically identical with the parent.
whereas in sexual reproduction that involves 2 parents the off spring born contains a genetic makeup that is a combination of 2 parents and thereby not genetically identical.
Answer:
adaptation-the inherited characteristic that increases an organism's chance of survival and to reproduce.
fitness -the ability of an organism to survive and reproduce in its environment
